Teamviewer used to work correctly (at least as far as I needed it to) before the update tp 14.1.3399, since that update was installed I get nothing. The tray icon is there, and click on it displays a menu, but selecting anything from that menu, including 'exit teamviewer' does nothing at all. I cannot even see my user id to test if I can connect to it from my laptop.
Linux Mint 17.3, ancient hardware that still works.
